I cannot understand why this fails. Does a DOMElement need to be part of a Document?

$domEl = new DOMElement("Item"); 
$domEl->setAttribute('Something','bla');

Throws exception

> Uncaught exception 'DOMException' with message 'No Modification Allowed Error';

I would have thought I could just create a DOMElement and it would be mutable.

php xml dom
